DNP, officially labeled as 2,4-Dinitrophenol, is classified as an industrial chemical. The compound can often be found in pressure treated wood as a fungicide, in various dyes, used in photograph development and as an insecticide. Officially, while an industrial chemical DNP is pure poison.

High dosages of DNP can land a person in the hospital or cause death. The user should start at 200mg per day or less, depending on body weight. From there, slowly up the dosage slightly after a few days, if you can tolerate it. The biggest mistake guys make is when the dosage is upped too quickly because DNP has a 36 hour half life. As a result, the user can find themselves in trouble if dosed too high over a few days. This is because DNP will build up in the system, which will be a big issue as side effects get worse and worse.
